Colusa Subreach Planning (CSP) was initiated to develop a strategy for restoration of the ecosystem along the Sacramento River between the community of Princeton and the City of Colusa in Northern California. The objective of this ecosystem restoration is to restore the ability of the environment to support viable populations of native wildlife. This strategy was to be integrated with the flood management system, agriculture and other existing land uses. The Nature Conservancy (TNC) and SRCAF formed a partnership to conduct the planning program and funding was provided by the CALFED Ecosystem Restoration Program. This webpage serves as a repository of CSP documents.
This Colusa Subreach Planning Report was prepared to synthesize the results of the Colusa Subreach Planning and to identify recommended actions for future management of the Subreach. It also chronicles the activities that took place as part of CSP and summarizes the products of the planning process.
The Colusa Subreach Background Report is a basic information source for the subreach planning process. It provides a broad baseline information context for the consideration of the economic, social and ecosystem needs of the subreach.
This Colusa Subreach Background Report is a basic information source for the subreach planning process. It provides a broad baseline information context for the consideration of the economic, social and ecosystem needs of the subreach. It is intended to be a resource for the Advisory Workgroup and other stakeholders involved in the planning process including local landowners, governments and organizations, recreation and conservation interests and agencies involved in the management of wildlife habitat and the flood control system. It is also intended to be used by SRCAF and TNC staff as a reference work and repository of information regarding the Colusa Subreach Planning Area.
A report on a survey of landowners within the Colusa Subreach covering property characteristics, landonwer awareness of the Colusa Planning effort, trust in agencies providing information on restoration efforts, belief in outcomes following restoration, and contact information.
A concept plan for public access and recreation to be compatible with private and public land ownership, existing agricultural practices, and wildlife habitat conservation within the Colusa Subreach of the Sacramento River.
The Colusa-Sacramento River State Recreation Area (SRA) is located in California's Central Valley, immediately adjacent to downtown Colusa along the west bank of the Sacramento River. The development of this master plan is a part of Colusa Subreach Planning, which is a partnership between TNC and the Sacramento River Forum. The preparation of this master plan was recommended by the Colusa Subreach Planning Advisory Workgroup, and EDAW Inc. was chosen to prepare this document.
Initial Study and Mitigated Negative Declaration of the Colusa Subreach Wildlife Habitat Restoration Project at Seven Tracts along the Sacramento River between Colusa and Princeton
This report provides results from a detailed hydraulic analysis of planned riparian restorations on the Sacramento River between Princeton (RM 164.0) and Colusa (River Mile 144.4). This model was used as a tool for comparison to the previously published 1957 design profiles and the water surface profiles planned restorations.
This cultural resources investigation report provides results from a field and record search for restoration properties considered in the CSP.
